Slide to rotary switch conversion

I am rehousing a Behringer and I need to swap this 4-position slide switch for an off-board rotary to make it work. My best guess is that it’s a 2P4T, but I can’t find a specs sheet for the switch and there is no available schematic for the full circuit.

Does anyone know how to “translate” this slide switch to a rotary? That is, which pads/lugs on the slide and rotary correspond to each other, or at least how I can go about testing each switch to determine that?

Do you see a part number stamped on the switch anywhere?

There are few different configurations that might be inside, nothing we couldn't work out with a DMM if necessary though.

(Of course it'd be much easier with the switch removed, especially with that jumper between the pins)
 
No markings on the switch, but I'll post an update pic once I remove it. I am going to clip the legs to avoid risky desoldering, but I should be able to keep the rest intact.
 
This is the TP300. That SF300 doc is on my radar, but I'm trying to get another Behringer rehouse under my belt before I take on that monster!

Here is a gut shot of the switch:

Yeah, better to be really prepared for SF rehousing. My rehouse has been sitting on WIP box for a year and half after loosing my intrest on non working circuit. Tried to use rotary switch with option for Fuzz1+Boost&Fuzz2+Boost, but couldn’t get it work. I really should just check every trace contiunity or audio probe it, but haven’t had slightest motivation for it. :cautious:
